G'day Bob thanks for the reply. Great info

yeah she's already apart i used the method u described but i used a press to get the crank moving and finished it off with a punch. The boss and flywheel didn't come apart.

Good tip about the grease in the bearings, i'll wash mine out too.

Good idea about getting the top bearing in - didn't think of putting it on the crank first and then into the case! I'll just tap it in with a punch a little bit at a time all the way round.

I will pickup the new parts tomorrow, hopefully it will up and running Thursday

thanks again
matt
